T 0 M7 "LU/ZO'HL it may concern:

Be it known that we. JAMES R, Hanson and JOHN R. SHEPHERD, citizens of the United States, residing at Anderson, in the county of Anderson, State of South Carolina. have invented a new and useful Ring- Rail Brace for Spinning Machines; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to ring rails for spinning machines and has for its object to provide a connecting means between the lifting rods and the ring rail, whereby the rail will be prevented from warping or moved from its place during its operation.

A further object is to provide a connecting means between a lifting rod and a ring rail, said connecting means comprising a transversely disposed member pivoted on a reduced portion of the lifting rod and provided with set screws adjacent its ends, which set screws engage the under face of the ring rail and may be adjusted for preventing warping or displacement of the ring rail. Also to provide the upper end of the lifting rod with a second reduced portion which extends through the ring rail and is provided with a cap screw for holding the ring rail in place during the adjustment of the set screws.

Vith the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure l is a top plan view of a portion of a ring rail showing the lifting rod connection thereto. I

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1.

Figure 3 is a bottom perspective view of the transverse pivoted member carried by the lifting rod.

Referring to the drawings, the numeral 1 designates a portion of a conventional form of ring rail and 2 spindle openings therein. It has been found that ring rails warp and become displaced, particularly Warp longi- Spccification of LettersPatent. V -Pategflggd'fgfl'y 1}, 192g 1921. Serial No. 480,065.

, tudinally in such a manner that their lona reduced portion 7 which extends through an aperture 8 in the ring rail and has threaded in the upper end thereof a cap 9. The cap 9 securely holds the ring rail 1 on the reduced portion 7, thereby connecting the ring rail to the lifting rod 6; The ends 10 of the plate 4 terminate adjacent the edges 3 and a of the ring rail and have threaded therethrough vertically" disposed set screws 11, the upper ends of which engage the under face 12 of the ring rail and form means whereby pressure may be ex erted on the ringrail in combination with the cap 9 for preventing warping of the ring rail. Where warping has already taken place the transverse bow in the ring rail may be removed by adjusting the ad justing screws 11.

From the above it will be seen that a connecting device for connecting a lifting rod to a ring rail is provided, wherein warping or displacement of the ring rail will be prevented, and one which may be easily and quickly applied to a ring rail. It will also be seen that the parts have been reduced to a minimum and that manipulating the'adjusting screws 11, the amount of pressure applied to the ring rail may be varied.

The invention having been set forth what is claimed as new and useful is 1. The combination with a ring rail of a spinning machine, of a transversely dis posed plate disposed adjacent one side of said rail and set screws extending through said'transversely disposed plate and cooperating with the ring rail for preventing warping of the ring rail in one direction and for straightening the ring rail after warping.

2. The combination with a ring rail secured to a lifting rod, of means for preventing movement and warping of said ring rail in one direction and for straightening the rail after warping, said means comprising a transversely disposed plate carried by the lifting rod adjacent one side of the ring rail and adjusting screws extending through the transversely disposed plate and engaging the surface of the ring rail.
